The direct detection of GWs by LIGO/Virgo collaboration has ushered in an entirely new era of gravitational-wave astronomy [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}. To data, the LIGO/Virgo/KAGRA collaboration has announced the detection of more than ninety confident GW events in the Gravitational-Wave Transient Catalog (GWTC) [5]}, [6]}, [7]}. These signals are produced by the coalescence of compact binaries, including binary black holes, binary neutron stars, and black hole-neutron star binaries. The GWs of these events, carrying valuable information about local spacetime properties of the compact binaries, allow us to explore the extreme gravity regime of spacetime, where the fields are strong, non-linear, and highly dynamical. This has enabled a lot of model independent tests of general relativity (GR) by LIGO/Virgo/KAGRA collaboration [11]}, [12]}, [13]}, [14]}, [15]}, [16]}. All the tests to date have confirmed that GW data is consistent with the predictions of GR.
